I wish it was so autumn but I've brought this up before over the last few years with varying answers such as  "single shot weapons mutated into guns perform a different type of basic attack than a regular single round gun attack so they shouldn't get the bonus" or just being ignored.

this isn't just a recent change.

I don't really know what you're talking about here, this was working for me last update, and I linked exactly the thread that sparked the change in the first place.

For the last few years every time I've tested using a sword mutated into gun my shell effects have always been the same as multi round guns, not single round guns.

On live just now  with blaze shell my Hisen did the same as a yang, the same it has been doing for the last three months. 

Hisen - 6 shell damage, 70 over charge damage -blaze shell
Auto pistol- 6 shell damage, 70 over charge damage- blaze shell
Excel sniper - 17 shell damage, 120 over charge damage- blaze shell.
